Beth Bhatt

Beth Bhatt has studied the CIP/KIP family of cyclin-dependent kinase inhibitory proteins p21 and p27 as critical mediators of cell cycle arrest and their complex roles in cancer suppression and promotion. Her research characterized the p53-p21 axis as the primary effector of G1/S checkpoint arrest following DNA damage, and how p21 induction triggers stable senescence in response to oncogene activation. She has investigated the paradoxical roles of p27 as both a tumor suppressor when nuclear and an oncogene-promoting factor when cytoplasmic and phosphorylated in cancer cells. Her work bridges cell cycle checkpoint biology with cancer metabolism, stem cell biology, and therapeutic senescence strategies in cancer treatment.
